ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Qatented April 30, 1907.

Application filed May 31,1905. Serial No. 263.199.

Be it known that 1, JAMES T. Ki'r'rnnnen, a citizen of the United States, residing at Stilwell, in Cherokee Nation, Indian 'lerritory, have invented certain new and useful Improvements in Gas-Generators, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to acetylene gas generators.

One object of the invention is to provide a comparatively inexpensive, simple, durable and eflicient generator of the character stated embodying such characteristics as to enable the rapid generation of gas for lighting or other purposes' Another object of the invention resides in the provision of an acetylene gas generator of such character that a pure white light may be obtained and wherein the gas will not be contaminated with foreign substances, but on the other hand will be purified in its passage from the generator to the main l'eed lines.

Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings and 1nrrticularly pointed out in the appended claims, it being understood that changes in the form, proportion, size and minor details may be made Within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings; Figure l. is a vertical sectional view of one form of my invention. Fig. 2 is a horizontal sectional view through the purifier. Fig. 3 is a vertical sectional view of another form of my invention.

Referring 110w more particularly to the accompanying drawings the reference character 1 designates a hollow base, upon which is mounted the section 2 within which latter is the fixed bell 3, the said hollow base forming the purifier.

Connected to the opposite sides of the base or purifier 1 are upwardly directed pipe connections 4 and 5, the latter being screwthreaded at its upper end, as at 6. The hell 3 is suspended within the shelf or section 2 by means of an angular pipe connection 7 whose horizontal portion 8 terminates in a downwardly directed pipe 9, which latter is exteriorly screw-threaded, there being an ordinary union 10 connecting the extension 9 and the pipeh to hold the hell 3 in its proper position and by means oi which the bell may be readily detached from communieation with the pipe 5. A valve 11 .is arranged in. the line of the angular pipe 7, and there is another valve 12 arranged in the nipple 13 arranged at one side ol the purifier l, the pur pose of the said valves being hereimilter stated.

heir the hell or gas cell 3 is suspended within the shell or section 2 and the valvel 1 is opened, and the valve 12 closed, and by allowing water to enter the tank 2, the air within the gasometer will pass through the pipe connections 7, 8 and 5 into the purifier l and out ol the latter in an upward course through the pipes and out of the latter through the air valve 14 arranged at the upper end ol the latter, the said air valve l-t, ol course, being opened at the same time the valve 1-1 is opened, the valve or cock 15 in the service pipe 16 being closed during the transit of the air ove r the course just stated.

In order to purity and clean the purifier 1 the extension t) of the angular pipe connection 7 maybe disengaged l'roni the upper end ol the pipe 5 and water poured thereinto lor circulation within the purifier llOlll which latter it may be drawn through the pipe connection 13 by opening the valve 12.

Arranged. within the hell in any suitable manner near the top thcreol is a perforated carbid cell 17 having its lower end tapered as at .18, there being a suitable gage or other means (not shown) painted or otherwise ar ranged upon the inner Pace of the shell or sec- 9 tion 2 for the purpose of determining the height of the water within the gasometcr.

\Vhen it is desired to generate the g t the valves 11 and 12 are closed and the air cock l i opened. Before operating the valves and cock in the manner stated, water is poured into the section 2 therebetween and the hell 3, the water passing upwardly within the bell 3 to the bottom ol the carbid cell 17, the water contacting with the carbid resulting in the generation of gas, the thus generated passing outwardly through the pipe 7. While the valve 11 is closed, the gas cannot pass downwardly through the pipe 5, and consequently there is more or less pressure in the pipe 7 and the upper portion of the bell 3, this pressure of gas serving to act upon the water column within the bell 3 to counterbalance the water column. In other words, the gas pressure tends to force the Water \Vi thin the bell 3 downwardly therein and upwardly therebetween and the shell or section Now when it is desired to send the generated gas through the service pipe 16, the air cock l i is closed, and the valve 15 of the service pipe 16 bein -opened together with an opening of the valve 1 1, causing generated gas within the upper end of the hell 3 and the angular pipe 7 to pass downwardly through the pipe 5 and into the purifier 1, in which latter the gas is compelled to take a circuitous course, by reason of the deflecting plates 19, as clearly shown in Fig. 2 and finally outwardly of the purifier and then upwardly through the pipe 4i to the service pipe 16 from which it may be emitted in regulated quantities by proper manipulation of the service pipe valve 15.

From the foregoing it will be seen that my generator is of a comparatively simple, and inexpensive nature and that it may be readily and easily operated. It will be also seen that the generator may be readil cleaned and that by reason of the circuitous course of the generated gas through'the puriner, the gas is rendered perfectly pure, that is, free from particles of lime and steam thereby giving life to the service pipes. In the passage of the gas from the gasometer, particles of lime and steam are liable to mingle with the gas, and it will be appreciated that in the event of such cominingling or the contamination of the gas with such matters, the latter will be eliminated from the former by reason of the purifier. It will also be understood that the gas is cooled by reason of its retarded movement through the circuitous course in the purifier, there being water in the latter for the cooling as well as purifying purposes.

Another feature to be appreciated is that there is absolutely no, chance of waste of the generated gas, for when the valve 11 is opened the water rises with a pressure of such character as to drive or force the gas through the said pipes and purifier.

By reason of the water entering within the gasometer and the balancing of the same with respect to the carbid cell as the result of the generation of the gas there is no danger of explosion and in the event that the gas should take fire it would be shut oil in the purifier cell by contacting with the water within. the cell, the gas, as will be observed entering beneath the level of the water.

From the foregoing it will be understood that the gas cell or bell 3 is rigidly held within the section or shell 2 in any suitable manner, but in Fig. 3 of the drawings there will be seen a flange 20 at the bottom of the gas bell 3, by which the latter is secured rigidly at its lower end to the shell or section 2, the said fiange 20 being perforated, as at 2]. to permit of the passage of water from between the bell 3 and shell 2 upwardly into the bell. ll ith the exceptions just referred to this form of generator is the same as the one already described.

What is claimed is I A gas generator comprising a cylindrical body having a purifier located in its lower end, a partition dividing the purifier from the remainder of the body, a valved gas inlet pipe communicating with the purifier adjacent its bottom, said pipe being extended upwardly and turned laterally and thence extended downwardly into the body, a bell supported by the pipe within the body, a foraminous c-arbid receptacle supported within the bell and in spaced relation thereto at all points, a gas conducting pipe leading from the purifier adjacent the partition in the body of the generator, and an air outlet valve leading from the pipe for permitting withdrawal of air from the bell before formation of gas therein.

In testimony whereof, I'aifiX my signature, in presence of two witnesses.
